Every start of an air compressor is accompanied by a huge mechanical inertia of the piston or screw; Each unloading load cycle causes repeated impacts on electrical components. Universal starters are prone to premature aging or protection misalignment under this operating condition. SPX high-quality Magnetic Motor Starter for Air Compressor deeply integrates magnetic starting technology with knowledge of the air compressor industry. It is not only a switch, but also a protection system that deeply understands the working logic of the air compressor. The original intention of its design is to ensure seamless coordination between the drive motor and the compressor host, and to stably convert electrical energy into pneumatic power.
The main contact adopts a special formula of silver based alloy and is supported by a reinforced structure, which can easily cope with the instantaneous impact of up to 7-10 times the rated current when the air compressor motor starts, and has extremely strong resistance to welding.
The optimized coil and magnet design enables the contactor to quickly and without vibration engage and release during frequent loading and unloading cycles of the air compressor, with a mechanical lifespan far exceeding the requirements of the standard AC-3 application category.
The built-in electronic overload protection unit can distinguish between normal overload starting process and abnormal "locked rotor" or "overload" current curve, prevent misoperation during normal motor acceleration stage, and quickly disconnect in case of true overload.
The Magnetic Motor Starter for Air Compressor provides a standard auxiliary input interface that can directly receive safety signals such as high temperature, low oil pressure, and sensor failure from the air compressor unit. Once an abnormal signal is received, the machine will immediately shut down, achieving deep protection of electromechanical integration.
The internal components adopt anti loosening fixation and seismic layout, and the shell can be optionally equipped with a higher protection level (such as IP55), effectively resisting common vibrations, oil mist, and dust in the compressor room.
Optimize the internal heat dissipation path of the Magnetic Motor Starter for Air Compressor to address the possibility of continuous operation, and ensure stable temperature rise and performance without degradation during long-term operation.
The main motor control of oil injected or oil-free screw machines and large piston machines in the factory's gas source center.
Magnetic Motor Starter for Air Compressor is used for the electronic control starting part of diesel electric motor units in construction and mining, which can withstand bumps and temperature differences.
Silent oil-free air compressors that provide air sources for laboratories and medical equipment require smooth start stop and sensitive protection.
The Magnetic Motor Starter for Air Compressor serves as the local control unit for a single air compressor, receiving start stop commands from the central controller and providing feedback on its status.
